Research on flexible allocation strategy of power grid interactive buildings based on multiple optimization objectives

Abstract

The imbalance between power supply and demand is increasing around the world. As an important basis for the coordination between supply side and demand side to solve the problem of supply and demand balance, the rational formulation of demand response strategy is very important. Aiming at the shortcomings of current demand response strategies in optimizing power flexible allocation, this paper establishes a flexible allocation strategy model under three different objectives of flexible optimization, economic benefit, and energy conservation to realize energy scheduling and flexible optimization under different objectives. The accuracy and rationality of the flexible allocation strategy are verified through experimental comparison. The maximum fluctuation value of the electricity load is 115 W in all electricity parity periods of the experimental days, accounting for 4.9% of the building electricity load, avoiding the occurrence of secondary peak electricity consumption. The power flexibility value provided by the strategy can reach 143% of the building electricity load before the demand response, making the building can be more flexible to face the power supply and demand balance problem of the grid.
